How to access to a IIS website externally?

Question

I've created a web in asp net core and it is published in IIS and works well accesing in my local network, but now I need to access in another pc out of my network.

My ip info is this:

Public IP ......................: 190.62.96.84

IPv4. . . . . . . . . . . . . . : 192.168.1.5

subred . . . . . . . . . . . . : 255.255.255.0

Gateway. . . . . : 192.168.1.1

I've set the site like this:

I've created a rule in my firewall with the port 8080

And finally I set Add a port forwarding like this:

I've also used the port 80 instead 8080 but no success... What I am doing wrong? There other way to access to my website externally?

Thanks in advance!
